Fatty Acid- and Tocopherol-Pattern in Oil Seeds

Abstract

Diets should contain 1 I.U. Vitamin E/g polyunsaturated fatty acids (PUFA). This requirement is fulfilled in decreasing order by hazel-nut, almond, copra, oilpalm-kernels, oilpalm-mesocarp and maize. In pistachio-nuts, hickory-nuts, groundnuts, walnuts, sesame and poppy-seed the Vit. E/PUFA-ratio is between 0.8 and 0.15. But these figures may vary even within a plant species, because cultivation of 6 sunflower-varieties in temperate and tropical climate as well as the analysis of safflower varieties differing in linoleic acid revealed a genetical and environmental variability of the Vit. E/PUFA-ratio.
